Embedded AC drive

Alternating current (AC) motors have over a century of history. During the last decades, they have dominated the market for motor drives used in industrial and consumer applications. But in the case of variable speed drives, there were some areas where DC motors were the only option for quite long, especially when torque control or a high dynamic control was required. This is now changing as the availability of compact and effective hardware solutions lets vector control expand to cost-sensitive areas like home appliances and consumer electronics.
